Allodesmus Baculum Replica measures 9.0 inches. Allodesmus Baculum Replica is museum quality polyurethane cast. Made in USA. Allodesmus uraiporens is the scientific name. Our precise Baculum can be used as a teaching tool, museum baculum exhibit, home decor baculum, or office decor baculum. Segment of the Buena Vista Museum of Natural History.
The baculum is used for copulation and varies in size and shape by species. Its evolution may be influenced by sexual selection, and its characteristics are sometimes used to differentiate between similar species.
A bone in the penis allows a male to mate for a long time with a female, which can be a distinct advantage in some mating strategies. Allodesmus kelloggi or Allodesmus uraiporensis is an extinct genus of pinniped from the middle to late Miocene of California and Japan that belongs to the extinct pinniped family Desmatophocidae. Allodesmus or Allodesmus uraiporensis measured about 8 feet long and weighed up to 800 pounds.
Allodesmus had the specific anatomical features found in modern polygynous pinnipeds: strong canines for fights between bulls and teeth with well-defined growth zones, a result from periodic fasting (in order to defend their harem, males would not take to the sea to feed during the breeding season). Miocene sea mammal from Caliornias Sharks Tooth Hill Bob Ernst Collection.
The fossil record of Allodesmus kelloggi or Allodesmus uraiporensis pinnipeds (seals, fur seals and walruses) is globally distributed, spanning from the late Oligocene to the Holocene. This record shows a complex evolutionary history that could not otherwise be inferred from their extant relatives, including multiple radiations and iterative ecomorphological specializations among different lineages, many of which are extinct.
Allodesmus sinanoensis and A. packardi were previously assigned separate genera, Megagomphos and Brachyallodesmus, respectively, but many authors questioned this generic distinction, and the cladistic analysis by Boessenecker and Churchill (2018) found no support for this generic scheme.
Atopotarus, referred to Allodesmus kelloggi by some authors (e.g. Mitchell 1966), is distinct from Allodesmus by the absence of a prenarial shelf and M2, double-rooted cheek teeth, a small, triangular postorbital process, and a mastoid process projecting ventral to the postglenoid process.
